Description

Sharp crystals of anglesite (?) (to 12 mm) encrusted (or perhaps completely replaced) by microcrystalline lime-green bayldonite (?). A few localised botryoidal aggregates of bayldonite (?) have crystallised on the pseudomorph faces. 

The specimen is in the collection of Scott Rudolph. The location in the mine is not recorded but the paragenesis and habit are strongly indicative of the first oxidation zone.
